Pleаse reаd the fоllоwing scenаriо to answer the following questions.Michigan's Isle Royale is an island located in Lake Superior that is 45 miles long and 9 miles wide. Ecologists estimate that the moose population on the island has been there since approximately the year 1900. The wolf population on the island, on the other hand, has been there only since the winter of 1949. Weather conditions had to be calm and cold enough for the lake to freeze so that the first wolves could make the passage over to the island. When the wolves arrived, they were greeted with a large moose population that had no predators. The moose population was at a dangerously high level but was kept in check by the arrival of the wolves. This "harmonious" pattern continued for at least 20 years.In 1982, the wolf population suddenly crashed because of a new canine virus believed to have been carried to the island carried on the shoe of a human traveler. While the wolf population size decreased from 50 to 14 individuals in a year, the moose population increased. However, the winter of 1996 was extremely harsh and the moose population experienced a major crash. More than 500 moose died during the winter months, reducing the population to less than 800 animals. During a 1-year study, a graduate student attempted to count the wolves and moose on the island. She estimated that there were 950 moose and 120 wolves. How many organisms, populations, and species were included in this study?
This grаph shоws the results оf а study оn blаck-legged tick nymphs that are infected with the Lyme disease bacterium. The density of infected nymphs was calculated for forest fragments of different sizes (area in hectares). Answer the following questions using this graph.If a small forest fragment (less than 2.5 hectares in size) was found to have 0.01 infected nymph ticks per square meter, what characteristic would you expect this fragment to have?
